This page report the time delay of all Latches available on Yaskawa portfolio and the dedicated devices applicable for it.
1. Disclamer
This application note includes supplementary information not contained in the official manual. The content is derived from laboratory testing but has not been reviewed or approved by the quality department. It is provided solely for informational purposes to assist in understanding Yaskawa products. Yaskawa assumes no liability for the accuracy, completeness, or applicability of this information. Only the information contained in the official technical manual is considered verified and authoritative.
2. Latch delay graphical concept
For an architecture with Servopack:
For an architecture with SLIO counter module:
In this document, only delay 1 will be documented.
- Delay 0 is sensor supplier specific
- Delay 1 represent the response time of a latch and is the most important value for the user
- Delay 2 is Yaskawa specific. It represents the internal cycle time of the device. Since it is always faster and modulo of Delay 3, it is negligible.
- Delay 3 represent the communication cycle time (Slicebus or EtherCAT cycle time) defined by the user and update of the information in the Data List/GDS port.
3. Yaskawa portfolio Latch inputs
| Device Name | Number of latch input (voltage) | Delay 1 / Latch response time | Minimum time ON of the signal | Comment |
|---|---|---|---|---|
| Sigma 5 large Capacity 200V/400V | 2 (24V) | 3µs delay (constant) + 0.5µs jitter from Off to On and 1.5µs jitterfrom On to Off. | Off --> On : 3.5µs On --> Off : 4.5µs |
The photocoupler delay of the CN1 (Delay 1) is NOT compensated internally. The user can program internally a correction in his code |
